双语阅读 | 如何停止打鼾?

How Can I Stop Snoring?如何停止打鼾?何雅蕙 供稿Snoringhappens when the muscles in the tongue, roof of your mouth and throat relax and constrict airflow. “You can’t get a full breath of air, so things startvibratingas they try to allow you to breathe — and the vibration is the snoring sound,” said Dr. Kent Smith, a sleep dentist in Dallas and former president of the American Sleep and Breathing Academy.当人们舌头、口腔顶部和喉咙的肌肉松弛时,它们会阻塞气道,导致人们打鼾。来自达拉斯的睡眠牙医、美国睡眠和呼吸学会前主席肯特·史密斯博士说:“当你不能呼入足够的空气时,你的肌肉组织会开始振动,以让你正常呼吸。而这个振动的过程就是鼾声的来源。”Men are about twice as likely to snore as women are, and it can be caused by a number of things, including allergies, aging, a cold or even just thedistinctiveshape of your throat. Your weight may also play a role.男性打鼾的可能性大约是女性的两倍。打鼾有很多诱因,包括过敏、衰老、感冒,甚至只是因为你的喉咙形状独特。同时,体重也有一定的影响。Once you know you are a snorer, even a subtle one, it might be worthwhile to get a sleep test from a sleep clinic, Dr. Smith said. Most of the time, the first one can be done at home in one night and will tell you if your snoring is a symptom of a larger problem, likesleep apnea, based on how many times per hour it interrupts your sleep. Whether or not your occasional wood sawing is tied to wider problems, there are steps you can take to lower the night noise.史密斯博士说,一旦你发现自己打鼾,即使不严重,也应该去睡眠科做一个睡眠测试。大多数情况下,第一次测试可以在家里用一晚上的时间完成。该测试会记录每小时打鼾干扰你睡眠的次数,然后可以诊断出打鼾是否表明你的身体其实有更严重的问题,比如睡眠呼吸暂停综合征。无论你那锯木头一样震耳欲聋的鼾声是否指示出身体有恙,以下这些缓解打鼾的招数都值得你参考。Sleep on your side.侧睡About half of snorers with sleep apnea in one Israeli study were found to stop when they changed positions. There are pillows available to help you sleep on your side and shirts that make it uncomfortable to roll on your back. For the D.I.Y.-types, you can trysewingsome tennis balls onto the back of your night shirt.以色列的一项研究发现,约有一半患有睡眠呼吸暂停综合征的打鼾者在改变睡眠姿势后会停止打鼾。专门设计的枕头可以帮助你维持侧身睡眠,还有特制的睡衣可以使你仰面朝天睡觉的时候感到不舒服。让你自己尝试的话,可以试试看把几个网球缝在睡衣的背面,能达到相似的效果。Strengthen your tongue.锻炼你的舌头One of the most common causes of snoring is when your tongue slides back in your throat. The simplest way to prevent this is with a daily set of tongue exercises. But doctors said it can take weeks to have an effect and most people are notdiligentin keeping them up.打鼾的一个最常见的原因是你的舌头滑向喉咙。预防这种情况的最简单方法是每天做一套舌头练习。但医生说,这可能需要几周时间才能见效,而且大多数人都做不到持之以恒。Weight loss.减肥Another way for some people to decrease snoring is to lose weight. Body Mass Index (BMI) is reliably connected to snoring and sleep apnea, doctors said, though every throat is different. Losing weight will decrease the pressure on yourwindpipeand allow more air to pass.还有一个缓解打鼾的方法便是减肥。医生表示,尽管每个人的喉咙都不尽相同,但身体质量指数与打鼾和睡眠呼吸暂停综合征有着密切的联系。减肥可以减少气管承受的压力,能让更多空气通过气管。There are also a wide range of “anti-snoring” devices available to buy online, most totally worthless. Chin straps, nose clips and strips, nostril dilators — be wary of them, doctors said, they don’t work for everyone. Ahumidifiermight help you sleep better by moisturizing your nose and throat, but it probably can’t stop you from snoring.网上也可以买到各式各样的“防打鼾”器具,但大多数完全无效。防打鼾产品包括下巴带、鼻夹和鼻带、鼻孔扩张器等,但医生建议大家谨慎购买,因为它们并不是对每个人都有效。加湿器或许可以通过湿润鼻腔和咽喉改善睡眠,但它无法防止你打鼾。【VOCABULARY】1.snorev.打鼾,打呼噜2.vibratev.振动3.distinctiveadj.独特的4.sleep apnea睡眠呼吸暂停综合征5.sewv.缝制,缝上6.diligentadj.勤奋的7.windpipen.气管8.humidifiern.加湿器(封面图片来源于摄图网,版权归摄图网所有)

双语阅读 | 为什么洗澡时常常会灵感乍现?

Why Do We Have Great Ideas in the Shower?为什么洗澡时常常会灵感乍现?曹艺凡 供稿Alice Flaherty, one of the most renowned neuroscientists researching creativity has an answer for us when it comes to why you get your best ideas in the shower. An ingredient that's very important for us to be creative is dopamine: The more dopamine that is released, the more creative we are.人为什么总在洗澡的时候灵感爆发?创造力研究领域最著名的神经科学家之一,爱丽丝·弗拉赫蒂为我们提供了答案。产生创造力的其中一个至关重要的因素是多巴胺。释放的多巴胺越多,我们就越有创造力。Typical triggers for events, that make us feel great and relaxed and therefore give us an increased dopamine flow are taking a warm shower, exercising, driving home, etc. The chances of having great ideas then are a lot higher.常见的令人感觉舒适、放松,从而促进多巴胺分泌的活动,包括洗个热水澡,锻炼身体,开车回家等等,在这些时刻,灵感乍现的几率会高很多。Especially if you have thought long and hard all day about a problem, jumping into the shower can turn into what scientist call the "incubation period" for your ideas. The subconscious mind has been working extremely hard to solve the problems you face and now that you let your mind wander, it can surface and plant those ideas into your conscious mind.特别是如果你已经为一个问题绞尽脑汁想了一整天,走进淋浴间的瞬间就是科学家所说的进入了想法的“孵化期”。潜意识里你一直在非常努力地解决面临的问题,而你现在洗澡的过程就是放松思维,让灵感浮出水面、进入到你的意识里的过程。Lastly, after you have received an influx in dopamine, can be easily distracted by an extremely habitual task like showering or cooking, a relaxed state of mind is absolutely important to be creative.最后,多巴胺水平上升后,你会很容易被习惯性的事件分散注意力,如洗澡或做饭。放松的心态对创意是至关重要的。Why is a relaxed state of mind so important for creative insights? When our minds are at ease, we're more likely to direct the spotlight of attention inward, toward that stream of remote associations emanating from the right hemisphere. In contrast, when we are diligently focused, our attention tends to be directed outward, toward the details of the problems we're trying to solve. While this pattern of attention is necessary when solving problems analytically, it actually prevents us from detecting the connections that lead to insights.为什么放松的精神状态对创造力的产生如此重要?当我们的思想处于轻松状态时,我们更有可能将注意力的焦点转向内部,转向从右脑远程发出的联想流。相比之下,当我们努力想集中注意力时,我们的注意力往往是向外的,转向我们试图解决的问题的细节。虽然这种注意力模式在分析性地解决问题时是必要的,但它实际上阻碍了我们去发现产生灵感的联想。That’s why so many insights happen during warm showers. For many people, it’s the most relaxing part of the day. It’s not until we’re being massaged by warm water, unable to check our e-mail, that we’re finally able to hear the quiet voices in the backs of our heads telling us about the insight. The answers have been their all along, we just weren’t listening.这就是为什么灵感乍现常发生在洗澡时。对许多人来说,这是一天中最放松的时刻。直到我们被温暖包围,不再想着查收电子邮件,我们才能够听到我们脑海中安静的声音,向我们诉说灵感。答案一直都在,只是我们没有在听。【Vocabulary】1.dopamine n. 多巴胺2.incubation n. 孵化3.influx n. (人、资金或事物的)涌入4.emanate v. 表现;散发5.hemisphere n. (球体的、地球的、大脑的)半球(封面图片来源于摄图网,版权归摄图网所有)

双语阅读 | 可以为服装申请专利吗?

Can You Patent Clothing?可以为服装申请专利吗?曹艺凡 供稿If you've just finished working on a new line of clothing, you're probably wondering whether you can protect it with a patent? The USPTO (United States Patent and Trademark Office) issues design patents that protect the aesthetics or ornamental appearance of an object and utility patents that protect the functional aspects of an article of clothing. So, can a patent protect your clothing?如果你刚刚完成了新一季的服装设计,你可能会好奇是否可以为其申请专利?美国专利及商标局(USPTO)可授权外观设计专利,用以保护产品富有美感或具有装饰性的外观设计;还可授予实用专利,用以保护服装的功能性设计。那么,专利可以保护你的服装设计吗?The short answer is yes, you can patent clothing using a design patent or utility patent. Patenting your clothing will allow you to restrict others from using, making, selling, and importing the patented clothing without your express permission.回答是肯定的,你可以为服装申请外观设计或者实用专利。一旦你的服装取得专利,他人就不得在未经你明确许可的情况下使用、制造、销售和进口该专利服装。You'll have the exclusive right to make and sell your clothing line, you will also be able to license the design or the invention of your clothing to third parties in exchange for a licensing fee. Also, if you wish, you can sell the patented design to another party.你将拥有制造和销售该系列服装的独家权利。此外,你还可以授权第三方使用该服装设计或发明,以赚取授权费。另外,如果你愿意,可以将专利设计出售给另一方。If the piece of clothing or apparel that you want to protect has a new, functional aspect, you can file a utility patent application. Utility patents protect functional items, including clothing that has a new and unique function.如果你想保护的服装具有新功能,那么可以提出实用专利申请。实用专利保护功能性产品,包括具有全新独特功能的服装。Problems with Protecting Clothing with a Patent利用专利保护服装的不足Now that we have covered how you can protect an article of clothing using either a utility patent or design patent, it’s important to understand the shortcomings associated with patent law protecting clothing.前文已介绍如何利用实用或外观设计专利来保护服装,那么了解利用专利法保护服装有哪些不足就十分重要了。It often takes the USPTO 20 months to approve or deny a design patent application and this is simply too slow in the fashion industry where trends tend to move fairly quickly. Often times, the design that’s sought to be patented is already out of fashion by the time the patent office issues the design patent. The USPTO does offer an expedited means of obtaining a design patent, but even then it takes 10 to 12 months to get a design patent approved.美国专利及商标局通常需要20个月的时间来通过或拒绝一项外观设计专利申请,但是时尚界的更新换代非常迅速,这个审批速度实在太慢。大多数情况下,在专利局通过外观设计专利时,申请专利的设计已经过时。即使美国专利及商标局提供了获批外观设计专利的快捷方式,也需要至少10到12个月的时间。In addition, although many makers of unique clothing designs will benefit from patenting their new designs, it is often cost-prohibitive for some people.此外,尽管许多拥有独特服装设计的制造商因其设计的专利保护而获益,但对一些人而言,申请专利的成本往往太过高昂。If you're an individual designer, you should expect to pay between $1,740 to $3,980 for an attorney to prepare and file your design patent application.如果你是独立设计师,你要预备1740至3980美元聘请律师,为你准备并提交设计专利的申请。【Vocabulary】1. aesthetics n.(审)美学2. ornamental adj. 装饰的;点缀的3. apparel n.(商店出售的)服装4. expedite v. 加速5. attorney n. 律师(封面图片来源于摄图网,版权归摄图网所有)

瑞典科学家因对早期人类的研究而获得诺贝尔医学奖Swedish Scientist Wins Nobel Prize in Medicine for Research on Early Humans刘立军 供稿TRANSCRIPTSwedish scientist Svante Pääbo won the Nobel Prize in medicine on Monday for his discoveries on human evolution. His work shows how our immune system works differently from our long-ago ancestors, the Nobel group said.New methodsPääbo has led the development of new methods that permit researchers to compare the genes of modern humans, also known as Homo sapiens, and that of some human relatives, like the Neanderthals and Denisovans.Scientists first found Neanderthal bones in the mid-19th century. But looking at their genetic code, or DNA, helps them fully understand the links between species. Pääbo studies the time when modern humans and Neanderthals went separate ways as a species. That was around 800,000 years ago.Anna Wedell is chair of the Nobel Committee. She said, “Pääbo and his team also surprisingly found that gene flow had occurred from Neanderthals to Homo sapiens, demonstrating that they had children together during periods of co-existence.”This movement of genes between ancient human species affects how the immune system of modern humans reacts to infections, such as the coronavirus. People outside Africa have 1-2 percent of Neanderthal genes.Discovery of a new human speciesPääbo and his team also recovered some DNA from a tiny finger bone found in a cave in Siberia. This led to the recognition of a new species of ancient humans they called Denisovans.Wedell described this as “a sensational discovery.” With that information, researchers showed Neanderthals and Denisovans to be related groups. They split from each other around 600,000 years ago. Denisovan genes have been found in up to 6 percent of modern humans in Asia and Southeast Asia.“By mixing with them after migrating out of Africa, Homo sapiens picked up sequences that improved their chances to survive in their new environments,” said Wedell. For example, Tibetans share a gene with Denisovans that helps them live in high mountain areas.Nils-Göran Larsson is a Nobel Assembly member. He told the Associated Press, “Svante Pääbo has discovered the genetic makeup of our closest relatives.

练习 | 欧洲在能源危机期间转向柴火

欧洲在能源危机期间转向柴火Europe Turns to Firewood during Energy Crisis刘立军 供稿TRANSCRIPTEurope's energy crisis has forced some people to turn to less costly heating sources, such as firewood.But as demand increases, the public is facing rising prices, shortages and even reports of firewood theft. Foresters are using GPS devices to follow their logs while others fear the environmental impact of increased air pollution and tree cutting.In Moldova, Tudor Popescu splits firewood that will heat his home in the capital of Chisinau. As the nights turn colder, the load of firewood has been growing higher around him - his supplies for the coming winter.In the past, Popescu depended on natural gas for warmth in the mornings and firewood at night. But gas is now in short supply, following Russia's major cut to gas exports.Russian energy business Gazprom has threatened even more reductions."I won't use gas anymore, so it's going to only be wood," Popescu said. "But what I have isn't enough."The demand for firewood in Europe is not limited to poorer nations like Moldova. Germany, Poland and the Czech Republic's state-owned forests are seeing much stronger demand for the limited amounts of firewood they sell as part of their sustainable forest programs.The German foreign ministry has reported getting requests for firewood from people who had never sought firewood before. The people seemed not to know that the firewood process takes two years. That is how long it takes to fully dry the wood so it will burn in wood stoves, said the forestry office in the southwestern state of Hesse.German forest rangers also report increased incidents of people gathering fallen wood in forests, often not knowing it is illegal.State forests in the Czech Republic also report increased demand for firewood. The government sells the wood for use at home, only. Officials say they’ve had to limit the amount of firewood sold to individuals.In Poland, demand for small firewood from state forests increased by 46% through the end of August from a year earlier. Larger firewood demand was up 42%. A spokesman for Poland's State Forests said, "small firewood is probably the cheapest heating material in the EU countries." He said theft of firewood is also on the rise.To prevent theft in Germany, the forestry department is experimenting with hiding GPS devices in logs. The German state of North Rhine-Westphalia is the latest to try the technology. Foresters in neighboring Hesse have been using GPS devices since 2013 and say they have been able to solve several thefts that way.Austrian police recently warned people to watch for those claiming to sell firewood online. Police in Germany had issued similar alerts.Germany's statistics agency says prices for firewood and wood products used in home heating rose over 85% in August from a year earlier. Even so, heating with wood is still less costly than natural gas. Gas costs 20.9 cents per kilowatt hour of heat, while wood products cost 14.88 cents.In Britain, prices of firewood also are going up. Company Certainly Wood says it has seen "a massive increase in demand" even though the price is 15 to 20% higher than last year.In Denmark, the demand for wood-burning stoves is growing along with demand for firewood itself. The Danish sales site DBA said searches for wood-burning products have increased by over 1,300% in the past year.At the same time, government officials and environmentalists have warned Danes about the risk of burning firewood. The smoke produced can be dangerous and adds to pollution, they say, and the tree loss adds to climate change problems.I'm Caty Weaver.VOCABULARY1. sustainable adj. involving the use of natural products and energy in a way that does not harm the environment (对自然资源和能源的利用)不破坏生态平衡的,合理利用的。例如:sustainable forest management合理的森林管理2. ranger n. a person whose job is to take care of a park, a forest or an area of countryside 园林管理员;护林人QUESTIONSRead the statements.

练习 | 再生蔬菜既减少浪费又省钱

再生蔬菜既减少浪费又省钱Regrow Vegetables to Reduce Waste, Save Money刘立军 供稿TRANSCRIPTGardening is a natural way to reuse leftover materials. For example, using leftover plant material to enrich soil, also called composting, is a good way to reuse uneaten food.Growing food from parts of plants not used in cooking also reduces waste and saves money.Instead of throwing away or composting the bottoms or tops of vegetables when preparing them, you can grow them into leafy greens or other produce right in front of your window. Produce like beets, celery, scallions and leeks, and romaine lettuce can be regrown in this way.It is important to note that these methods are not likely to produce plants that will grow well in your garden. Regrowing plants is not a good way to replace young, growing seedlings. But they are likely to make enough greens for side dish to add to a dinner or two. And regrowing plants can be a fun project.Leftover produce will grow best with a lot of sunlight. Use slightly warm water and replace it every day or two to avoid the growth of bacteria. Do not worry if the part of the plant under water becomes a bit slimy. However, if the whole plant starts to turn brown, throw it in the compost and start over.BeetsBeets are a good plant to regrow because they provide two side dishes: the large root and the tasty greens. You cannot regrow a beetroot indoors from a cutting, but you can regrow more leafy greens.To do so, cut off the top four centimeters or so from a beetroot and place it cut-side down in a dish that contains just enough water to keep the cut end under water.New leaves will regrow from the top within a few days. And you can start harvesting them in two weeks or so. This method also works with the similar vegetables, parsnips and turnips.CeleryFor celery, cut eight centimeters off the bottom of a head of the plant. Then, cut off a very thin piece from the bottom of the eight centimeter piece. Place it right-side up in a container and pour in five centimeters of water. New growth will appear from the center in just a few days.Scallions and leeksFor scallions and leeks, cut the white part from the bottom of the stalk. Then place it root-side-down in a container holding 2.5 centimeters of water. If the stalk outgrows the container, move it to a larger one. New growth will be harvestable in about two weeks.Romaine lettuceFor romaine lettuce, cut eight centimeters off the bottom of a head of the plant, then remove its outermost leaves. Place the eight-centimeter “heart” in a container to which you have added a little over a centimeter of water.Within a week, a small growth will appear from its center.
